Vostok Island, also known as Staver Island, is an uninhabited coral island in the central Pacific Ocean, part of the Line Islands belonging to Kiribati. Other names for the island include "Anne Island", "Bostock Island", "Leavitts Island", "Reaper Island", "Wostock Island" or "Wostok Island". The island was first sighted in 1820 by the Russian explorer Fabian Gottlieb von Bellingshausen, who named the island for his ship ''Vostok'' (the name means "East" in Russian). == Geography, flora and fauna == Vostok is located at and covers a land area of 24 hectares. Its nearest neighbors are Flint Island, 158 km south-southeast; Caroline Atoll, 230 km to the east; and Malden Island, 709 km north-northwest. It is 1.3 km in length, and is triangular-shaped. Beaches on the island range between 25 and 50 meters wide, composed of coral sand and rubble. There is no lagoon or fresh water on the island, and no known freshwater lens. Vostok's major portion is covered with a pure stand of ''Pisonia'' trees rooted in moist peat soil one meter thick. These trees, with heights of up to 30 meters, grow so densely that no other plants can grow beneath them.〔 The herbs ''Boerhavia repens'' and ''Sesuvium portulac'' astrum round out the known vegetation. Coconut seedlings were planted on Vostok in 1922 and failed, although on the nearby islands of Caroline and Flint there are existing coconut palms.〔 Noteworthy fauna includes several species of seabirds, including the red-footed booby (''Sula s''ula), great frigatebird (''Fregata minor''), lesser frigatebird (''F. ariel''), black noddy (''Anous minutus''), white tern (''Gygis alba''), masked booby (''Sula dacty''latra), brown booby (''S. leucogaster'') and brown noddy (''Anous stolidus''). The Polynesian rat and the azure-tailed skink (''Emoia cyanura''), together with coconut crabs and green turtles, completes the known land fauna. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vostok Island」の詳細全文を読む スポンサード リンク
